"We're busier than usual. Demand is way up," says Dr. Daniel Meges of Care Alliance Health Center, who's been treating the poorest of the poor this week. "You see a lot of frostbite, hypothermia, people sick with the flu or a cold."

Among those he treats at area homeless shelters is 31-year-old Elizabeth Curtis, who is homeless and a recent transplant from Toledo.

"I go to the library and shelter to stay warm -- places like this allow me to get a checkup in the process," she said.

"The people that are exposed to the elements, are sicker than they usually are," Dr. Megis tells Channel 3. "There's a tremendous need to get them out of the elements No. 1. No. 2, we need to encourage them to spend the nights in the shelters rather than on the streets."
